This document discusses paraphilias and paraphilic disorders. Paraphilias are atypical sexual interests that are not inherently disordered unless they cause distress or impairment. Paraphilic disorders involve paraphilic behaviors that consume excessive time and cause problems. Major paraphilic disorders include exhibitionism, fetishism, frotteurism, pedophilia, sexual masochism, sexual sadism, and voyeurism. The document outlines these disorders and notes prevalence rates. It also discusses child molestation, diagnosing sex offenders, atypical paraphilias, rape prevalence and types. The next lecture will cover causes and prevention of paraphilic disorders.
